Very nicely decorated flat, same as how the photos show. Unlikely to find a better condo at this price. The hosts are very responsive and helpful, offering affordable pickup service from the airport.
Although the flat itself is not close to the city center, it only takes 5 mins walk to the BTS station and you can expect to arrive at Sala Daeng or Siam station in 20 - 30 mins time. There are quite a few restaurants and convenient stores nearby, and loads of street food stalls on the way to the BTS station. Moreover, they are generally cheaper than the ones you can find in the city center, so can't really complain about the location.
The only minor problem was that there were small cockroaches in the kitchen, but I guess it's an unavoidable issue in tropical countries.
Overall, highly recommended.
